Sample Output 59: Game Dice Roller

In the examples above we have created functions that returned a numeric
value. Functions may also be created that return a string value. A string
function, like a variable, has a dollar sign after its name to specify that is
returns a string.

1 # repeatstring.kbs
2 # simple string function – make copies
3
4 a = "hi"
5 b = repeat(a,20)
6 print a
7 print b
8 end
9
10 function repeat(word,numberoftimes)
11 result = ""
12 for t = 1 to numberoftimes
13 result ;= word
14 next t
15 return result
16 end function
Program 60: Repeating String Function

hi
hihihihihihihihihihihihihihihihihihihihi

Sample Output 60: Repeating String Function

Observe in the function samples, above, that variables within a function exist
only within the function. If the same variable name is used in the function it
DOES NOT change the value outside the function.
